Abstract. There has been substantial expansion of oases in the Northwest of China in recent decades; however, research has largely focused on desertification rather than oasification and its associated mechanisms. Based on the description of desertification in arid regions and other regions, and analysis of oasification in arid or hyper-arid areas, we firstly elucidate the theoretical relationship between oasification and desertification. We then examine the current understanding in oasification research, and propose that this will enhance our understanding of desertification through the integration of studies of oasification. Finally, we suggest three potential topics for future oasification research. We also propose a simple conceptual model for the identification of an appropriate oasis size under different land uses, including the crucial assessment of associated uncertainties. Based on the analysis of oasification research from an epistemological and methodological perspective, we suggest that oasification should have equal research status to desertification in arid regions.
